LOCK FOR AUTOMOBILES.

Application filed April 2,

My invention relates to gear locks for automobiles.

It has been found that in practice the operator is apt to forget to lock his machine upon leaving it, and an object of my improvements is to provide against this contingency. In the accompanying drawing 1 show by way of illustration my invention in connection with the kind of gear lock patented to me in Patent 51,280,589, October 1. 1918, and in connection with the form of apparatus used with the Studebaker automobile.

Referring to the accompanying drawing,

Figure 1 is a sectional elevation of an apparatus embodying my invention in connection with a part of the gear case and a part of the gear shifting apparatus, and the lock therefor.

Fig. 2 is a section on the line Ill-H, Fig. 1.

Flg. Fig. 1.

Fig. i is a detail section on the line IVIV, Fig. 2.

Fig. 5 is a perspective view of one of the insulating blocks.

a is a part of the gear casing. Z), Z) are shifting rods which ca ry the shifting forks shown at 6 b 0, c are steel balls in a cavity extending between the rods 6, Z). (Z is a vertical rod having a cam (Z at its lower end which cam is adapted to force the balls 0, 0 part way into slots in adjacent sides of the shifting rods Z2, b to lock the gearing when the rod cl is turned to one position, and to release said balls when the rod is turned in the other position. 0 is a pin lock barrel at the top of the rod (Z, adapted to actuate the same. A key is inserted in a slot at the upper end of the barrel 0, which is a conventional construction, and is, therefore, not particularly shown.

7 represents the primary wire of the ig- 3 is a section on the line IIIHI,

. nition circuit and g the return wire where such is used. A 7L are binding posts to which the wires 9 and are secured. These binding posts engage through insulating.

blOCrIS h, 71, and secure elastic strips 7L 7f to the inner surface of said blocks. Said blocks are secured by bolts h 72, to the inner surface of the casing a.

Serial No. 629,504.

51' is a contact cam secured upon andadapted to rotate with the rod (Z.

This cam is either of solid conducting material or is surrounded by a band of conducting material as represented in the drawings.

When the rod (Z is turned to the position to permit the balls 0, 0 to enter the transverse aperture in which they are placed out of ening the plete. in Fig.

circuit between the wires 9 and g so that the ignition circuit shall be comhen turned to the position shown 1 and in full lines in Fig. 3, said cam is out of contact with the strips 7?, ll,

and the ignition circuit is broken.

hen the operator leaves an automobile he always breaks the electric circuit and removes the key.

With the above apparatus the act of breaking the electric circuit will also look the gearing so that if the electric circuit is broken the automobile must be locked so that its gearing cannot be used.

What I claim is:

In an apparatus of the kind described, the combination of a change-speed-gear casing, an ignition circuit, two parallel gear shifting rods adapted to reciprocate therein, a cavity in said casing extending between said rods, balls in said cavity, a vertically extending rod having a cam at its lower end in said cavity between said balls, a pin look at the up er end of said vertical rod accessible from above'said casing, an insulating block on the interior vertical. block, a

wall of said casing adjacent to said rod, an elastic contact strip on saiu bindlng post exteudlng through the wall of said casing and engagingv said strip and binding it to said block, a cam on said vertical rod adaoted to en a 'e said strip PD b 1 tion.
